In the disposition of its markings, and the general colour and texture of its plumage, this singular Ara9ari 
differs remarkably from all others yet discovered ; the beak being more brilliant, and the jdumage of the 
body less ostentatious and gaudy. Nor does it present a less striking difference in its habitat, all the other 
species being found in the lower and warmer regions, while according to information received from an 
authentic source, the Grey-hreasted Ara9ari inhabits the mountains, and is to be found only on the highest 
wooded portions of the Andes, for which elevated and cold situations the full and downy texture of its 
plumage, so different from the close feathering of the Ara9aries in general, admirably adapts it. The specific 
name given to this bird relates to the beautiful silvery lustre which prevades the fine grey tints spread ov^er 
the breast and under surface. 
This interesting bird, with many other valuable specimens of Ornithology, was sent to me by my esteemed 
and valued correspondent D. Christie, Esq., of Popayan, Columbia; and I here gladly avail myself of the 
opportunity of testifying my sincere acknowledgements for the many favours received, as also for much 
important information. 
As I have never met with this bird in the museums of this country or in those I have visited on the 
Continent, and Dr. Latham’s notice of a “ Blue-throated Toucan ” being too vague and unsatisfactory to 
afford any tangible data, I have every reason for concluding this species to have been hitherto undescribed. 
Of the two specimens received, one is deposited in the Museum of the Zoological Society of London. 
Inhabits Columbia.
